Image: The twin galaxies NGC 4496A and NGC 4496B

NGC 4496 in the constellation Virgo consists of two spiral galaxies, NGC 4496A (upper large galaxy) and NGC 4496B (lower galaxy). They are in the same line of sight from Earth but located at quite different distances, and ...

Is the universe a fractal?

For decades, cosmologists have wondered if the large-scale structure of the universe is a fractal: if it looks the same no matter the scale. And the answer is: no, not really. But in some ways, yes. Look, it's complicated.

Hubble spies spiral galaxy NGC 2566

This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 2566, which sits 76 million light-years away in the constellation Puppis. A prominent bar of stars stretches across the center of this galaxy, and ...

HD 65907: The mysterious case of the resurrected star

The star HD 65907 is not what it appears to be. It's a star that looks young, but on closer inspection, it is actually much, much older. What's going on? Research suggests that it is a resurrected star.

Astronomers detect new 1.9-second pulsar using FAST

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China, astronomers have discovered a new pulsar with a spin period of about two seconds. The newly detected pulsar, designated PSR J1922+37, was found ...

Back to the past: The death of stars reveals their birth

A new article published in Universe describes an approach that looks back from the deaths of stars to their births, allowing the so-called initial mass function (IMF), i.e. the way in which star masses are distributed after ...

A new class of cosmic X-ray sources discovered

An international team of astronomers, led by researchers from the Astronomical Observatory of the University of Warsaw, have identified a new class of cosmic X-ray sources. The findings have been published in The Astrophysical ...

Using Jupiter as a dark matter detector

The nature of dark matter has been a hotly debated topic for decades. If it's a heavy, slow moving particle, then it's just possible that neutrinos may be emitted during interactions with normal matter.
